[Samba] Demote Win2008R2 DC Fail

[Anderson Hoffmann do Carmo]

Hi.

I am using a Windows Server 2008R2 as primary DC and a Ubuntu Server 16.04
as secundary DC with Samba 4.3.9 (from repository/apt-get)
I am transfered FSMO rules to Samba and I am try to demote Windows, but
fail!
The error is:

The operation failed:
The active directory domain services could not find another domain
controller to transfer the remaining data on the partition
DC=DomainDnsZones,DC=testead,DC=minhaempresa,DC=com
"the specified domain does not exist or can not be contacted"

​Any ideia?

​The Samba DC it's OK and operational
